Hofsjökull ice-cap
A new cauldron confirmed
An excursion on 9 October 2013 has confirmed that a new cauldron has formed in one of Iceland's ice caps, Hofsjökull, as a result of a jökulhlaup from a subglacial, geothermal area.
This image from Landsat 8, NASA USGS, shows the northern half of the ice cap Hofsjökull (enlarge).
A new patch, visible at the bottom of the image (see arrow), has now been confirmed as a cauldron (~64°49,5‘N; 18°52‘W) at around 1700 m above sea level.
Below is a map of Iceland with Hofsjökull tagged (maps.google.com). Travellers are advised to be very careful during journeys on Hofsjökull. Crevasses surround the new cauldron.
